Seems like POST values are lost when .htaccess RewriteRule used. GET values are OK. How to fix?

Question

Several days ago I had a question about removing index.php from the address bar, so the address of the page looks shorter and better. The shortest solution of this problem was (RewriteRule ^index.php / [L,R=301] in the .htaccess file). And it works!

Since I put that string into the .htaccess, some pages are redirected to the main page. I spent a lot of time to guess, why. As I understand, the answer is: with RewriteRule ^index.php / [L,R=301], $_POST parameters are not sent to the next page. $_GET parameters are OK. Once I remove RewriteRule ^index.php / [L,R=301] from .htaccess, everything becomes fine as usual. Why does it happen and how to fix that?

Thank you.

Answer 1

You could try using [L,R=307] instead. 307's must not change the request-method according to the spec, but I don't know how browser implemented 307.

But the root of the problem is the use of <form action="____/index.php" ...

Just leave the action empty to POST to the current url e.g.

Answer 2

I'm using something like:

<IfModule mod_rewrite.c>

RewriteEngine on

RewriteCond %{REQUEST_URI} !^/(css|images|js)/

# don't rewrite existing files, directories and links

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l


# rewrite everything else to index.php

RewriteRule .* index.php [L]

</IfModule>

And its working for all requests, rewriting it via index.php file. If you need to redirect 301 (which stands for Moved Permanently code) check out this question: Is it possible to redirect post data?
